I have Nexus 4 Android 4.4.4 version, Build KTU84P.
Since yesterday my call log is not updating i.e. If I make a new call or receive the call, that number is not been shown in call log. I restarted the mobile phone but problem is not rectified.
FYI, I had killed some cached running process using Settings/ Apps but not sure which process may have resulted into this and how can I restart the same process.
